In Australia, if you apply for a 457 visa as a software developer, you must show 3-5-10 years of experience in software development, "or a closely related field". It's much easier to be in the first situation than having to demonstrate the field is closely related, e.g. they don't specify DBA nor team lead on that list.

Of course if you apply with humans, they may understand that a master of Linux and Java dev adds a lot of value to a dev team. But HRs aren't humans.
